Why are you so adamant that this be incorporated into Bitcoin, rather than a block chain of your own design?
It's pretty obvious that few people (if any) other than you and bji want this "feature".
I think a better dialog would ensue if you would describe what you think is the most likely scenario for Bitcoins in the future. This would include your best guess of their future valuation, and the reasons for your estimated future valuation. As a defender of Bitcoins, you can then justify its current design as much as you want.
